Dipesh, As the adoptive mother of a "Shaken Baby" who is now 6 years old who has recently had a real scare with subdural bleeds I may be able to offer a similar experience with explanation....... Matthew was severely shaken at 2 1/2 months of age and had both the brain bleeds and retinal hemorrages. At the age of 6 years he was thought to have a tethered cord and so an MRI was obtained of brain and spinal cord. The folks in radiology were alarmed when they saw that he had massive subdural hematoma's. We were questioned about any recent falls, etc..... There were no known injuries. After seeing a neurosurgeon at Duke University and a repeat CT we learned that he had two hematomas, one on each side of his brain about 1 cm thick and each covering the entire hemisphere. Basically it was described as a "carpet of blood". They also told us that this was from his original injury during infancy, that the bloods can stay there permanently...... I would think that if a hematoma is present 6 years after injury that one month is not unusual by any means. Karin
